Hello my dear friend,
It is not necessary that if you are connected to Wi-Fi,you have access to the internet.In your area you may be connected through Wi-Fi,but router may not be connected to the external network.Wi-Fi shows connected means you are connected to the computers in your area but it is not necessary that you have access
to internet.

It happens because the wifi service provider have restrict others to use the internet.You can easily get connected to the WI FI because it is not secured with a key.Try troubleshooting your connection if you have not correctly configured your connection.
